Wondering how to incorporate science, technology, engineering, and math PLUS collaboration, critical thinking, problem solving, and digital literacy into the PreK-K curriculum? You can do it with project-based learning units and scaffolded activities through which young students design, create and use learning/play centers. The book presents 8 units, each broken down into 5 phases with specific guidelines, options for adjustments, and suggestions for parent support. This " learning by doing" approach is fun, and it allows learning to come naturally as children who are bubbling with different abilities, backgrounds, and ideas work together.
